The Vikings defense has ranked fourth in red zone scoring (44.19 percent) and fifth in points allowed per game (18.9) since Zimmer has become Minnesota's head coach.

To further illustrate the point, Vikings.com points out that Minnesota was last in the league in points allowed in 2013. In Zimmer's first season the Vikings improved to 11th in 2014, then jumped up to fifth last season.

Additionally, Williamson adds that all of last year's starters return to this year's squad.

"Mike Zimmer has created this up-and-coming defense in his image. It's loaded with exceptional young talent at every level. It could be the best in football."
